VALVE-CAP.

n 3; l Specication of Letters Patent.

Patented sept. es, i915.

Tflipplz'u'iation ed January 15, 1915 Serial No 2464' moved therefrom Without the necessity of rotating the cap to thread ythe latter onto' the valve and remove the same therefrom.

lt is also my purpose to provide a valve cap which when applied to the valve airy Vbe rigidly and securely fastened thereto so as toprevent accidental displacement of the cap, and wherein 'the component parts or the cap will be so correlated and arranged as to eliminate the possibility of derangement.

Furthermore, I aim to provide a cap of the type set forth which Will embrace the desired features of simplicity, eliciency and durability,-Which may be manufactured and marketed at a minimum expense and Which -may be readily applied to any type of tire valve new in use Without changing the construction 'of such valve.

With the above and other objects in View,

the invention consists in the construction,

combination and arrangement of parts hereinafter set forth in and falling Within the scope of the claims.

ln theaccompanying drawing; Figure 1 is a vieu7 in side elevation of a tire valve equipped with a cap constructedin accordance with the present invention, a portion of the telly of the' Wheel being shown in longitudinal section. Fig. 2 is a longitudinal sectional view through the cap applied to the valve, the latter being shown in side elevation. Fig. Sis aperspective View of the cap and securing devicenemoved from the valve. Fig'. l is av longitudinal sectional view through the cap securing devices and jam nut removed from the valve.

. Referring noW to the drawing in detail,

A designates a, portion of the ellybf' a Wheel carrying an inflatable tire b equipped Withthe usualintlating valve c projecting through Aan opening in the felly and extending-toward the center of the Wheel, as usual. The outer surface of the body of the valve c is threaded throughout its entire length and the outer end of the body is circumferentially reduce to form a nipple al' exteriorly threaded to eceivethe usual valve ca llhreaded onto thebody of the valve is f. 3am nut 1 designed to abut againstthe'im ner surface of the Wheel telly to hold the tire valve securely in position. Formed in the outer end of the jam nut 1, that is, the end of the nut engaging the telly, concentrically of the bore in the nut is a seat 2 and disposed Within the seat 2 is a Washer 3 forming an air tight joint between the outer end of the jamA nut and the felly. ln the present instance, the end Wall of the seat 2 vis convexed in cross section so that the Washer Willbe compressed against the felly. Formed in the opposite end of the jam nut 1 is a relatively deep seat 4 and seated upon the end Wall of the seat 4l is a washer 5 composed of rubber, felt or other suitable material. The side Wall of the seat 5 is screw threaded as at 6.

i' designates a cap constructed of metal or other suitable material and in the form of a tubular sleeve having one end closed and the other end open, as is usual in the construction of the valve caps ofiniatable tires of motor vehicles. Formed on the open end of this cap 7 is an outwardly projecting circumferential flange 8 that seats against the Washer 5 in the seat 4. when the cap 7 is slipped over the outer end of the body of the valve. Surrounding the cap 7 adjacent to the flanged end thereof and of a diameter slightly greater than that of the flange is a collar Qhaving the flanged end thereof screw threaded as at 9 to engage the threads 6 on the'vside Wall of the seat l and formed on the opposite end of the collar at diametrically opposite points are thumb pieces 12 whereby the collar may be revolved upon the casing to engage the threads 9 with the threads 6 and disengage such threads. In the present instance, an annular bead 1l is formed on the cap 7 and spaced apart from the'flange- Sand coperates Witlbthe flange 8 to prevent accidental yremoval of the securing collar 9 fromA the cap When the cap 1s removed from the body of the valve.

ln practice,.the cap 7 is slipped over the ,body of the valve and the ange 8 seats against the Washer 5 in the seat 4. The collar l .out ofthe lseat Ltithe cap'and collar may be '9 is now revolved under the action ofthe Wings orthumb pieces and the threaded Aend portion of such collarengages-the Wall of the 'seat A to clamp the flange 7 against the" Washer 5 and the latter against the end Wall of the seat 4, thereby effecting 'a Vsecure and rigid connection between the cap and n the body. To remove the cap it is only necessary .to give the collar 9 a fevv turnsin the opposite direction and when the collarmoves :lifted from-the valve box.

It avill be seen that'I have provided a4 i valve cap which may be .readily vand quickly applied to thei bodyBo-f the valve and removed y therefrom Without the necessity of turning the capv through a distance equal to the lengths'of the threads on the body.

l/Vhile I have herein shown and described A the preferred form'of' my invention by Way @of illustration, I Wish itto be understood *that I do lnot limit or confine myself to the precise details oit' construction herein described andqdelineated, as modification and 1 )the-claims Without departing from the spirit.

variation may be made Within the scope of' of the invention.

Iy fclaim 1. `rIhe combination with a tire valve, of a jam nut threaded onto the body of said -,valye and' having one end thereof formed f with a seat, a Washer engaging the end Wall of said seat, a cap surrounding the body of said' valve and adapted to slide onto and off ofthe same, a flange formed on one end of said'cap. and disposed Within said seatin engagement withA the Washer therein, and means for effecting a connection between the flanged end of saidcap and seat.

2. The Combination with a tire valve, of

a jam nut threaded onto the .body of said Lvalve and having one end thereof formed with a. seat, a cap surrounding the body of said valve and adapted to slide Aonto and offof the same and having the inner end there-- 'the same and having the inner end thereof formed with a flange disposed Within said seat, and a collar surrounding saldcap and threaded into said seat and engaglng the flanged end of said ca'p to hold the latter to.

said nut, said Cap being formed with an an nular bead acting to prevent accidental removal of said collar.

In testimony whereof I affix my signature in presence of two. Witnesses.
